Has anyone gotten System Update 4 to install and then automatically and silently download and install the recommended updates?

I get the program to install during mdt using:
systemupdate314-2008-5-15.exe -s -a /s /v" /qn"

and ive found that you need to create a batch file with:

Code:
 cmd /c "C:\Program Files\Lenovo\System Update\Tvsu.exe"
cmd /c TASKKILL /F /IM tvsukernel.exe
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update" /v "Languageoverride" /t REG_SZ /d "EN" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v "IgnoreLocalLicense" /t REG_SZ /d "YES" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v "DisplayLicenseNotice" /t REG_SZ /d "NO" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v "DisplayLicenseNoticeSU" /t REG_SZ /d "NO" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v "ExtrasTab" /t REG_SZ /d "NO" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v "RepositoryLocation1" /t REG_SZ /d "\\c-00008n002\updateretriever" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\General" /v "NotifyInterval" /t REG_SZ /d "36000" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\Scheduler" /v "SchedulerAbility" /t REG_SZ /d "YES" /f
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Lenovo\System Update\Preferences\UserSettings\Scheduler" /v "SchedulerLock" /t REG_SZ /d "LOCK" /f
cmd /c "C:\Program Files\Lenovo\System Update\tvsu.exe" /CM -search A -action INSTALL -repository \\mylocation\updates. -includerebootpackages 1,3,4 -noreboot -noicon
Can anyone verify this? Also is there a way to have it point to the internet for updates and not a network share?
